Yes, to the first question. If you go to a store that has the kiosk, you can do every bit of it at the store and you do t have to do anything else on your own.

I don’t know anything about that suppressor. You might go to different places and check out several different models. Unless you are going to use it on a pistol, there is not any reason to get the hybrid. For a rifle only, I would look at some other models.

There are a lot of places where you can get your barrel threaded.
